1,953,188 CONTROL DEVICE AND METHOD OF MAKING SAIME Harry E. Norviel, Anderson, 1nd., assignor to Delco-Remy Corporation, Anderson, Ind., a corporation of Delaware Application January 12, 1931, Serial No. 508,079

Claims. (Cl. 29-148) This invention relates to manufacture of a con.- trolling device for operating a mechanism, for example, the spark control lever of a distributor for an internal combustion engine. The mechanism to be controlled may be manipulated from an instrument board. More particularly the invention relates to the method of securing a wire provided with a hooked end to one end of an actuating rod. This rod may be located in a convenient place suitable for the operator.

One object of the present invention is to provide a novel and economical method of attaching the wire to the actuating rod. This is accomplished by providing the rod, at one end, with a pair of jaws, the jaws being separated by a.s1ot locating the hooked end of the wire in the slot intermediate the jaws, and then clinching the jaws about the hooked end of the wire to secure the wire to the actuating rod.

Another object of the present invention is to provide a flexible wire having a hooked end secured to the rod, the hooked end extending laterally of the rod to form a stop for movement of the rod.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing wherein a preferred embodiment of one form of the present invention is clearly shown.

Referring to the drawing 20 designates a controlling device. The controlling device comprises a tubular bushing or attachment member 21 having an enlarged head 22 adapted to abut against the outer face of an instrument board or panel 23. The instrument board is provided with an opening through which a screw-threaded shank the dian actuating rod 25. The outer end of the rod 25 extending beyond the instrument board has secured thereto a handle or knob 26 in any suitable manner, so that any movement of the handle is transmitted to the rod 25. In the construction here shown the inner end of the rod 25 is provided with a longitudinal slot 27 to provide a pair of jaws or lips 28. While the drawing illustrates a longitudinal slot formed by a saw, it is to be understood-that other forms of slits or kerfs may be used on the rod 25, which may in fact result in splitting the end of the rod or otherwise forming it so that it is adapted to receive a flexible wire 29. Thus the slits or kerfs are referred to by the term slot, and are meant to be inclusive of all forms of so preparing the rod end. The flexible wire 29 is bent at an angle or otherwise formed to provide an end 30. This end is then placed in the slot 27 intermediate the jaws 28 so that it protrudes above the outer surface of the actuating rod as illustrated in Figs. 1, 3 and 6. When the wire 29 is located in the slot 27, suitable mechanisms are used to clinch or squeeze the jaws 28 about the end 30, thus firmly securing the wire 29 to the actuating rod 25. The other end of the flexible wire 29 is connected in any suitable manner to a lever 31 of a distributor 32. The lever 31 controls the advance and retard movements of a timer mechanism inclosed in the distributor. The lever 32 is manually operated through the controlling device 20. It is to be understood, however, that the controlling device 20 is not limited in its application to such structures.

The end 30 of the wire 29 limits the movement of the actuating rod 25, in the first form of the threaded shank of the tubular member 34 is counterbored andcontracted upon a rib or bead 36 of a sleeve 37 to form a tubular fitting which provides an extension for the actuating rod 25. The sleeve 37 has a slot or groove 38 into which the end 30 carried by the rod 29 projects. The no end walls of the slot 38 limit the inward and outward movements of the actuating rod while the side surfaces of the slot 38 cooperating with the end 30 prevents the rotation of the rod 25 within the sleeve 37 and the bushing 34.

While the form of embodiment of the present invention as herein disclosed, constitutes a, preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. A controlling device comprising in combination; a bushing; a rod slidable in the bushing, said rod being provided with a pair of jaws, the jaws being separated by a longitudinal slot; and a flexible wire having a hooked end located in the slot intermediate the jaws, the jaws being deformed on both sides of the hooked end to rigidly secure the wire to the rod.

2. A controlling device comprising in combination; a rod provided with a pair of jaws, said jaws being separated by a slot; and a flexible wire having a bent end located in the slot intermediate the jaws, the jaws being deformed on both sides of the bent end to secure the wire to the rod.

3. A controlling device comprising, in combination, a bushing; a rod slidable in said bushing, said rod being provided with a slot bounded by jaws; and a flexible wire having an end portion bent at an angle to said wire and located in the slot intermediate the jaws, the jaws being deformed about the bent end to secure the wire to the rod and the transverse portion of said end limiting the movement of the rod in one direction.

4. A controlling device comprising, in combination, a tubular member; a sleeve member car- 'ried by said tubular member; an actuating rod slidable in said members, said rod having a slot at one end thereof to provide a plurality of jaws; a flexible member having a bent end, said end being located within the slot intermediate the jaws and extending beyond the outer surface of the actuating rod; the jaws being deformed on both sides of the bent end to secure the wire to the rod; and means on the sleeve member for receiving the end of the flexible member to limit the movements of the rod in either direction and to prevent rotation of the rod within the sleeve member.

5. The method of attaching a wire to a rod which comprises the steps of providing the rod with a longitudinal slot to receive a bent portion of the wire; and in deforming that portion of the rod provided with the slot on both sides of the bent portion so as to keep the wire within the slot.

6. The method of attaching a wire to a rod which comprises the steps including, providing the rod with a slot bounded by lips to receive a bent end of the wire, and in squeezing the lips on both sides of the bent end so as to hold the wire within the slot.

7. The method of attaching a wire having an L-shaped portion to a rod which comprises the steps including, providing the rod with aslot to receive the L-shaped portion of the wire and in deforming the rod on both sides of the L-shaped portion so as to hold the wire within the slot.

8. A controlling device comprising in combination; a bushing; a manually reciprocable rod guided by said bushing, a flexible wire having a hooked end fixed to an end of said rod and projecting above the surface of said rod, said hooked end cooperating with the adjacent end of said bushing to limit the movement of said rod in one direction, said rod having a trough to receive said hooked-end, said rod having the walls of said trough to be deformed on both sides of said projecting portion to engage and hold said wire securely upon said rod.

9. A controlling device comprising in combination a bushing; a manually reciprocable rod guided within said bushing; a sleeve provided with a slot secured to said bushing; and a flexible wire having an L-shaped end connected with said rod and projecting through said slot to limit the movement of said rod in either direction and preventing rotary movement of said rod relative to said bushing, said rod having one end notched to receive said L-shaped end and said rod being deformed on both sides of the L-shapedend whereby the wire is securely connected upon said rod.

10. A controlling device comprising in combination; a bushing; a manually reciprocable rod guided within said bushing; a sleeve provided with a slot secured to said bushing; and a wire bent at an angle to the length thereof to provide a stop and connected with said rod, said stop-
